Question

C++ Help. PLEASE include detailed comments and explanations. PLEASE follow the drections exactly. Thank you.

Define a class with the name BankAccount and the following members:

Data Members:

accountBalance: balance held in the account

interestRate: annual interest rate.

accountID: unique 3 digit account number assigned to each BankAccount object. Use a static data member to generate this unique account number for each BankAccount

count: A static data member to track the count of the number of BankAccount objects created.

Member Functions

void withdraw(double amount): function which withdraws an amount from accountBalance

void deposit(double amount): function which deposits an amount to the accountBalance.

void calculateMonthlyInterest( ): function which calculates the monthly interest and adds to accountBalance

void displayAccountInfo( ): function which displays the accountID, accountBalance, interestRate and count of the number of BankAccounts created.

Define the derived classes CheckingAccount and SavingsAccount from BankAccount with the following interest rates:

const double DEFAULT_INTEREST_RATE_CHECKING = 0.04;

const double DEFAULT_INTEREST_RATE_SAVINGS = 0.06;

If the AccountBalance of the CheckingAccount falls below $500 then a fee

of $50 is charged to the account.

const double DEFAULT_FEE_CHECKING = 50.0;

Use the following driver to validate your program:

#include <iostream>

#include <iomanip>

#include "SavingsAccount.h"

#include "CheckingAccount.h"

using namespace std;

int main()

{

     CheckingAccount jackAccount(1000);

     CheckingAccount lisaAccount(450);

     SavingsAccount samirAccount(9300);

     SavingsAccount ritaAccount(32);

     jackAccount.deposit(1000);

     lisaAccount.deposit(2300);

     samirAccount.deposit(800);

     ritaAccount.deposit(500);

     jackAccount.calculateMonthlyInterest();

     lisaAccount.calculateMonthlyInterest();

     samirAccount.calculateMonthlyInterest();

     ritaAccount.calculateMonthlyInterest();

     cout << "***********************************" << endl;

     jackAccount.displayAccountInfo();

     lisaAccount.displayAccountInfo();

     samirAccount.displayAccountInfo();

     ritaAccount.displayAccountInfo();

     cout << "***********************************" << endl << endl;

     jackAccount.withDraw(250);

     lisaAccount.withDraw(350);

     samirAccount.withdraw(120);

     ritaAccount.withdraw(290);

     cout << "********After withdrawals ***************" << endl;

     jackAccount.displayAccountInfo();

     lisaAccount.displayAccountInfo();

     samirAccount.displayAccountInfo();

     ritaAccount.displayAccountInfo();

     cout << "***********************************" << endl << endl;

     system("pause");

     return 0;

}

Code:

#include <iostream>

using namespace std;

class BankAccount{
public:
const int uid;
BankAccount() : uid(accountID++){
accountBalance = 0.0;
}
  
BankAccount(double balance1) : uid(accountID++){
accountBalance = balance1;
}
  
int get_actNumber() {
return uid;
}
void deposit(double amount) {
accountBalance = accountBalance + amount;
}
void withdraw(double amount) {
accountBalance = accountBalance - amount;
}
double get_balance() {
return accountBalance;
}
int count(){
return uid;
}
  
protected:
double accountBalance;
static int accountID;
};

int BankAccount::accountID = 100;

class SavingsAccount : public BankAccount {
public:
SavingsAccount(double balance)
: BankAccount(balance) {
rate = .06;
}
  
void set_interestRate(double rate) {
rate = rate;
}
  
double get_interestRate() {
return rate;
}
  
void postInterest() {
accountBalance += (accountBalance * rate);
}

void withDraw(double amount) {
if (accountBalance >= amount) {
accountBalance = accountBalance - amount;
} else {
cout << "Insufficient funds. Withdrawl transaction rejected, balance remains the same" << endl;
}
}

void displayAccountInfo() {
cout << "Interest Saving ACCT#:" << get_actNumber() << " Balance: $" << get_balance() << endl;
}

void calculateMonthlyInterest(){
accountBalance = accountBalance + (rate * accountBalance);
}
protected:

};

class CheckingAccount : public BankAccount {

public:

{
//_number = get_actNumber();

rate = 0.04;
}
  
void set_interestRate(double rate) {
rate = rate;
}
double get_interestRate() {
return rate;
}
void set_minBalance(double minBal) {
minBalance = minBal;
}
double get_minBalance() {

}
bool checkMin() {
if (accountBalance >= minBalance)
{
return true;
}
else
return false;
}
void set_fee(double fee1) {

}
double get_fee() {

}
void postInterest() {

}
void withDraw(double amount) {

cout << "insufficient funds. Withdrawl rejected, does not affect balance." << endl;
}
else {
if (accountBalance - amount >= minBalance) {
accountBalance = accountBalance - amount;
}
else
{
accountBalance -= (amount + fee);
  
}
  
}
}
void displayAccountInfo() {
cout << "Interest Checking ACCT#:" << get_actNumber() << " Balance: $" << get_balance() << endl;
}
void calculateMonthlyInterest(){
accountBalance = accountBalance + (rate * accountBalance);
}
};

int main() {
   CheckingAccount jackAccount(1000);
CheckingAccount lisaAccount(450);
SavingsAccount samirAccount(9300);
SavingsAccount ritaAccount(32);
jackAccount.deposit(1000);
lisaAccount.deposit(2300);
samirAccount.deposit(800);
ritaAccount.deposit(500);
jackAccount.calculateMonthlyInterest();
lisaAccount.calculateMonthlyInterest();
samirAccount.calculateMonthlyInterest();
ritaAccount.calculateMonthlyInterest();
cout << "***********************************" << endl;
jackAccount.displayAccountInfo();
lisaAccount.displayAccountInfo();
samirAccount.displayAccountInfo();
ritaAccount.displayAccountInfo();
cout << "***********************************" << endl << endl;
jackAccount.withDraw(250);
lisaAccount.withDraw(350);
samirAccount.withdraw(120);
ritaAccount.withdraw(290);
cout << "********After withdrawals ***************" << endl;
jackAccount.displayAccountInfo();
lisaAccount.displayAccountInfo();
samirAccount.displayAccountInfo();
ritaAccount.displayAccountInfo();
cout << "***********************************" << endl << endl;
system("pause");
return 0;
}

Output:

***********************************
Interest Checking ACCT#:100 Balance: $2080
Interest Checking ACCT#:101 Balance: $2860
Interest Saving ACCT#:102 Balance: $10706
Interest Saving ACCT#:103 Balance: $563.92
